Fujifilm Natura 1600

Natura 1600 was sold in Japan for use in the Fuji Natura point-and-shoot cameras, which were designed explicitly for shooting in low light without flash. The cameras had fast lenses (usually f/1.9) and the film was made to match: ISO 1600, tuned for available-light interior work in restaurants, bars, clubs, and the kind of evening shooting that defines a certain strain of Japanese social photography.

The grain is visible but well-organized for the speed class. Compared to Kodak's consumer 800-speed offerings pushed to 1600, Natura was cleaner. Compared to Portra 800 pushed to 1600, it was also competitive, which is remarkable for a stock that sold at consumer prices. The tonal response held shadow detail longer than expected at this speed, which is exactly what you want when shooting a lit face against an unlit room.

Color at ISO 1600 is warm in tungsten and reasonably neutral in daylight, with a slight golden cast that reads well in the contexts the film was designed for. Print it and the warmth integrates naturally. Push it further to 3200 and the grain becomes a strong graphic element but the tonal structure holds, which is more than most ISO 1600 films can say.

The reciprocity exponent is 1.10, though Natura 1600 was designed for available-light fast shooting rather than long exposures. A tripod and a multi-second exposure was not the intended use case. Zone Light Meter applies the correction past one second if you do try it.

Fujifilm discontinued it in 2017, years after the Natura camera line had wound down. Import buyers in the US and Europe had been ordering it through Japanese retailers for years before that. The remaining frozen inventory trades at high prices among collectors and shooters who know what it was capable of.
